Title: Yarn break detector
IPC: D01H13/16
Filed: 1959-05-25
Abstract: 932,949. Spinning processes; stop-motions. L. NAMENYI-KATZ. May 24, 1960 [May 25, 1959], No. 17678/59. Classes 120 (2) and 120 (3). In a method of detecting yarn breakages in textile machines, a beam of light is directed on to each yarn in turn and the light reflected from the yarn is caused to activate a photo-electric device adapted to inhibit an alarm signal. Presence of yarn withholds an alarm signal and absence thereof prevents operation of the inhibiting device and allows the signal to be produced. An alarm circuit may include a device which continues to operate the alarm after the beam has been moved to the next yarn. As shown in Fig. 1, which represents one station of a spinning frame, roving 16 passes through an eye 17 and an aperture 18 on a flyer arm 11, thence to a bobbin 14 rotatably supported on a reciprocating frame 15 and braked by a cord 19 and weight 20. A carriage 23, continuously travelling or traversing the length of a row of spindles 12, mounts a light source, e.g. a lamp and condenser lens 25, so as to throw a beam on to each yarn as the carriage passes it. Light reflected from each yarn passes through a lens 26 to a photoelectric device 27, e.g. a photo-transistor. A series of contact strips 28 are engaged by a travelling contact 29 on carriage 23 so that carriage circuits are electrically energized (to switch on the lamp and bring electrical circuits into operation) just before the carriage reaches each spindle and are de-energized sometime after the carriage has passed the spindle. The reflected light causes device 27 to deliver a signal to an amplifier 32, Fig. 2, the output signal of which operates an electromagnetic relay to close a normally open holding-contact RL1 and open a normally closed contact RL2 so that (a) coil RL remains independently energized from the power supply until contact 29 leaves strip 28 for the corresponding spindle, whereupon relay returns to inoperative condition and (b) engagement of an auxiliary contact 30 on carriage 23 with a fixed contact 31 (after carriage has passed the spindle and before contacts 28, 29 disengage) has no effect when yarn is intact. When breakage occurs, the relay remains in unoperated condition and contacts RL2 are closed so that an alarm circuit produces visual or audible signal. The alarm circuit is reset after the yarn is restored. An indicator may show which spindle requires attention and stop the spindle. A system capable of high-speed operation and independent of variation in room lighting, switching surges, and lamp failures comprises an oscillator to feed the source (whereby the light therefor is modulated) the amplifier being tuned to the frequency thereof, and a bi-stable multivibrator, separately set both to permit and to inhibit a relay-operated alarm, each connected to a Schmitt circuit, Figs. 1 and 4 accompanying the Complete Specification (not shown).

Title: Improvements in and connected with permutation locks
IPC: E05B37/02
Filed: 1922-06-27
Abstract: 200,686. Bettink, J. J. W., and Verwer, P. A. June 27, 1922. Locks, permutation; gated rings.- A hollow gated ring is closed by a curved sliding bolt locked in operative position by permutation rings mounted on the shackle and engaging balls carried in recesses in the bolt. The annular casing 1, Fig. 1, has a gap bridged by the curved bolt 2, operated by the finger piece 3. A second hollow casing 8, fixed within the casing 1 serves as a guide for the bolt to slide in. The bolt has notches into which fit balls 4 which in the position shown in Fig. 1, lock the 'bolt against withdrawal by abutting against flanges 5 on permutation rings 7. When the rings 7 are set for release, notches in the flanges 5 are brought opposite the balls, which can pass through them allowing the bolt to be operated. The inner casing 8 is slotted to allow the balls to move with the bolt. The casing 2 is cut into segments by the fitting of the rings 7, the whole being held together by the inner casing 8. In the form shown in Figs. 6 and 7, the casing 1 is ribbed as at 9, forming guides for the balls. The flanges 5 of the rings 7 only cut through the ribbed parts 9, leaving the trough parts 10 continuous so that the inner casing 8 may be dispensed with. In the form shown in Figs. 8 and 9, the locking balls 4 do not travel with the bolt when the bolt is operated, but move radially into slots 6 in the flanges 5 of the permutation rings 7 when these are correctly set, allowing the bolt to move. The rings 7 are supported by means of guide pieces 13, 14 fixed on the casing 1. The guide pieces 13 enclose a spring 17 supporting a ball 16 which clicks over depressions on the inner surface of the ring 7 to enable the ring to be set by sound. The bolt 2 may be a hollow tube with the seam facing inwards and may have a steel filling piece to prevent release by sawing through the bolt when it is bridging the gapped ring 1.

Title: Improvements relating to processes of and apparatus for extruding metals
Inventor: HORNE CAMPBELL CLOUSTON
IPC: B21C23/02
Filed: 1957-06-07
Abstract: 836,052. Extruding. WIGGIN & CO. Ltd., H. June 2, 1958 [June 7, 1957], No. 18193/57. Drawings to Specification. Class 83 (4). During the extrusion of a metal billet a back pressure in a direction opposite to the extrusion pressure is applied to the leading end of the extruded product over substantially its full cross-sectional area whereby inner and outer layers of the moving metal are restrained from moving at substantially different speeds. The invention is of particular use in the extrusion of metal-refractory mixtures, copper-aluminium alloys or heat-resistant metals such as nickelchromium, nickel-chromium-cobalt, nickel-uranium-molybdenum-cobalt or nickel-iron-molybdenum alloys used in the manufacture by hot extrusion of turbine blades. The billet is machined, nickel-plated and then extruded through a die using a graphite lubricant. A secondary ram moving in a guide tube coaxially with the die orifice applies constant back pressure to the extruded product. The guide tube may form an extension of the die and both the die and guide tube are faced with a hard material. When composite billets are extruded the invention is stated to inhibit tapering of the core of the extruded product. Specific examples are given.

Filed: 1938-06-20
Abstract: 519,619. Pottery glazes. KING, A. June 20, 1938, No. 18300. [Class 56] [Also in Groups III, VI and VIII] The sedimentation volume of dispersed solids or predispersed liquids, in water or aqueous liquids (i.e., the volume attained by the dispersion under the action of gravity), is increased, and the rate of separation of such dispersions reduced, by mixing or distributing the dispersed material with a gelatinous colloidal precipitate the gel structure of which has not been'destroyed and which produces the desired effect by virtue of the mechanical support afforded to the suspended matter. Metallic hydroxides such as those of aluminium, zinc or copper are suitable for the process. The desired colloidal precipitate may be produced . in the presence of the dispersed substance, e.g., by the addition of ammonia to a solution of aluminium sulphate containing a dispersed powder. The method may be applied to the treatment of a paraffin emulsion comprising paraffin (B.P.) glycerine, water and aluminium hydroxide. The addition to the emulsion of 7 volumes of a suspension of gelatinous alumina containing 1 per cent. of Al<2>O<3> produces suspension which will not " cream " on prolonged standing. Products according to the invention are suitable for use in the manufacture of paints, especially oil bound water paints (titanium white pigment), for filling and coating paper, as glazes for pottery, pharmaceutical and cosmetic preparations (e.g., suspensions of calamine). Products obtained by the use of the activated gelatinous .alumina described in Specification 487,855, [Group III], are excluded from the scope of the invention.

Title: Improvements in apparatus employing pulse echoes
Inventor: BROWN THOMAS GRAHAM
IPC: G01S7/62
Filed: 1964-05-04
Abstract: 1,108,567. Pulse-echo distance-measuring apparatus; cathode-ray tube displays. SMITH'S INDUSTRIES Ltd. 4 May, 1965 [4 May, 1964], No. 18455/64. Headings H4D and H4T. In an intensity-modulated cathode ray tube display system for use with radar, echosounding, and ultrasonic flaw-detection apparatus, the sensitivity of the apparatus is varied for successive transmitted pulses and the echoes produced from a given reflecting object by the successive transmitted pulses are displayed spaced apart on the screen. In a flawdetection embodiment, echo signals from a testpiece 9 are displayed along the horizontal timebase of a cathode ray tube 14. The gain of an amplifier 11 through which the echo signals are passed is varied for successive transmitted pulses, and successive sweeps of the trace on the tube 14 are displaced in the vertical direction to produce a display in which successive echoes from a given object are displayed above each other. Comparison of the traces at different sensitivities enables large amplitude echoes (which result in defocussing of the luminous spot of the trace at high sensitivities) to be distinguished from small-amplitude echoes of extended flaws. Voltage waveforms for controlling the gain of amplifier 11 and for displacing the trace vertically may be of staircase or sawtooth form, are synchronized with the transmitted pulses, and may be derived from generators 17 or from ganged rotary potentiometers. In various modifications, the sensitivity of the apparatus may be varied by varying the amplitude of the transmitted pulses, varying the electrical damping of the transducer system (which may have separate or combined transmitting and receiving transducers), or varying the limiting or clipping level of an echo amplitude selector.
